Conversion of carbon dioxide to organic products
First Claim
1. An environmentally beneficial method of producing methanol by electrochemical reduction of any available source of carbon dioxide, which comprises:
- providing a divided electrochemical cell comprising an anode in a first cell compartment and a cathode in a second cell compartment that also contains a catalyst which is one or more of a substituted or unsubstituted aromatic heterocyclic amine selected from the group consisting of a pyrazine, a pyridazine, and a pyrimidine, both compartments containing an aqueous solution of an electrolyte;
providing carbon dioxide from an existing source into the second cell compartment; and
electrochemically reducing the carbon dioxide in the second cell compartment to produce methanol.

Abstract
The invention relates to various embodiments of an environmentally beneficial method for reducing carbon dioxide. The methods in accordance with the invention include electrochemically or photoelectrochemically reducing the carbon dioxide in a divided electrochemical cell that includes an anode, e.g., an inert metal counterelectrode, in one cell compartment and a metal or p-type semiconductor cathode electrode in another cell compartment that also contains an aqueous solution of an electrolyte and a catalyst of one or more substituted or unsubstituted aromatic amines to produce therein a reduced organic product.
